The colors, the backgrounds, flying a spaceship. It's absolutely beautiful. I think the way it taught you the game in the beginning was very good. The in-game music is pretty good and has it's own sound. I have turned it off but after a few hundred hours... it's been a while so I'll turn it back on soon.
Also, earlier in a conversation someone said that they had a problem with me because I was on CCP's case over lag. That isn't true at all. CCP considers lag to be a very high priority. As a CSM member with programming experience, I would be honored to do a briefing on their efforts. I agree with their priority of it.
If the situation arose where a CSM proposal significantly increased lag I would be highly critical of it.
